2 Claims. (Cl. 88-14) This invention relates to a bore scope for use in conjunction with firearms, such as rifles and the like, and more particularly to a device for inspecting the barrels.

The primary object of the present invention resides in the provision of a bore scope adapted to be received in the chamber of a rifle or similar firearm so that the barrel thereof may be easily and conveniently inspected for wear, obstructions and such other defects as may exist.

A further object of the invention resides in the provision of a firearms bore scope which has novel means for detachably positioning a mirror for ready substitution of one of different capacity for magnification and the like.

Still further objects and features of this invention reside in the provision of a firearms bore scope that is simple in construction, highly efiicient in operation, strong and durable, and which is adapted to be used in various types of rifles including automatic or lever-type rifles whereby the barrel may be conveniently and easily in spected by simply inserting the bore scope and holding the barrel up to a source of illumination.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this firearms bore scope, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a side elevational view of a portion of a rifle with the bore scope comprising the present invention operatively emplaced in the chamber thereof;

Figure 2 is an enlarged sectional view of the bore scope as taken along the plane of line 22 in Figure l; and

Figure 3 is an exploded perspective view illustrating the manner in which the bracket is associated with the sighting box 'of the bore scope.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates a suitable firearm, such as a lever action or automatic type rifle, with which the bore scope comprising the present invention and generally designated at 12 is adapted to be employed. The bore scope 12 is adapted to be utilized in viewing the interior of the barrel of the firearm so as to ascertain whether there are any existing imperfections in the barrel or any obstructions. Further, the amount of rust or corrosion inside the barrel can be readily ascertained by the use of this bore scope.

The bore scope 12 includes a tube 14 which has an arcuate wall 16 of a sighting box 18 either integrally formed therewith or afiixed thereto, as by welding or brazing. The sighting box 18 has two spaced end walls 20 and 22 as well as a side wall 24 and a front wall 26 welded, soldered, brazed or otherwise attached to the end walls 20 and 22 and to the tube 14. The front wall 26 is provided with a sighting aperture 28 and has a rearwardly extending flange 30 integrally formed therewith. A bracket 34 is provided and has an arcuate plate 36 Patented June 4, 1957 adapted to lie flush against the arcuate end wall 16. An enlarged block 38 may be provided which is suitably threaded, as at 40, for reception of a threaded screw or other suitable fastener 42 used to secure the bracket 34 within the sighting box. The bracket 34 includes a side plate 44 which forms the side wall of the sighting box 18. The bracket further includes an angularly disposed plate 46 terminating in an L-shaped flange 48 adapted to receive and hold a mirror 50 in position where the mirror 50 is angularly disposed at a 45 angle relative to the longitudinal axis of the tube 14 and whereby a person sighting through the sighting aperture 28 will perceive light rays entering the tube 14 and being reflected so as to allow observation of the condition of the interior of the bore of the barrel of the rifle. Of course, other brackets with other suitable mirrors may be utilized.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A device for inspecting the barrel of a chambered firearm comprising a tube, a sighting box afiixed to said tube communicating with said tube and having a portion thereof in alignment with the longitudinal axis of said tube, said sighting box and said tube being received in said chamber, a bracket secured to said sighting box, and a mirror carried by said bracket in said sighting box, said mirror having its reflecting surface extending at a 45 degree angle with respect to the longitudinal axis of said tube, the portion of said sighting box in alignment with said tube being an arcuate wall of semicylindrical configuration corresponding to a portion of said tube, said bracket having an arcuate plate lying against said arcuate wall, and a fastener detachably securing said arcuate plate to said arcuate wall, said bracket including a side plate extending substantially normal to said arcuate plate, said sighting box having an open side wall, said side plate closing said open side wall.

2. A device for inspecting the barrel of a chambered firearm comprising a tube, a sighting box afi'ixed to said tube communicating with said tube and having a portion thereof in alignment with the longitudinal axis of said tube, said sighting box and said tube being received in said chamber, a bracket secured to said sighting box, and a mirror carried by said bracket in said sighting box, said mirror having its reflecting surface extending at a 45 degree angle with respect to said longitudinal axis of said tube, the portion of said sighting box in alignment with said tube being an arcuate wall of semicylindrical configuration corresponding to a portion of said tube, said bracket having an arcuate plate lying against said arcuate wall, and a fastener detachably securing said arcuate plate to said arcuate wall, said bracket including a side plate extending substantially normal to said arcuate plate, said sighting box having an open side wall, said side plate closing said open side wall, said sighting box having a front wall oppositely disposed to said portion 'of said sighting box in alignment with said tube, said front wall having a sighting aperture therethrough.
